 back as the seventies.

 ran over courses of seven furlongs and under without 

 winning a race. 



Excluding from the offspring columns of the table 

 the 43 fillies, the six roarers, the blood-vessel breaker,

 twenty-five colts which won at seven furlongs or 

 were placed at one mile or over, we obtain the follow-

Assuming all the sprinting mares to be PP in 

 composition, the calculated result for RR sires mated 

 to PP mares is, of course, 325 PR. The appearance of 

 the 156 staying individuals in the offspring clearly 

 demonstrates that a very large number of these
